JAMES D. MEIGHER, on TITUSVILLE, PENNSYLVANIA, ASSIGNOE OF ONE-V HALF OF HIS RIGHT TO JOHN A. GOUTANT, E sAME PLACE.

" STILL FOR REFINIING PETROLEUM} SPECIFICATION forming part of Letters Patent No. 224,301, dated. February 10, 1880. Application filed A l n 1879.

To all whom it may concern: I

Be it known that I, JAMEs D. MEIGHER, of

Titusville, Crawford county, Pennsylvania,

have invented an Imprpved Still'for Refining Petroleum or Hydrocarbon Oils, of which the following is a specification.

The object of my invention is to prevent all coking or burning of the oil while being vaporized, prevent chilling, preserve a uniform to heat through the whole mass, cause more rapid vaporization, and preserve the color of the products, and, in making lubricating-oils,to prevent them from chilling and becoming black and stringy.

This I accomplish by the agitation of the whole body of oil' by mechanical contrivance while being vaporized by heat,- and at. the same time I introduce a current of heated air into the oil,.and in that manner assist the va- 2o porization and facilitate the flow of vapor through the pipes into the condenser.

In the drawings, Figure l is a view of the a vertical section through the still; Fig. 2, center; and Fig. 3, a horizontal section on line a- 3 just above the bottom of the still. 1

A is the still; B, the setting or fire box; O, a vertical shaft passing through a packingboX in the top of the still and kept in position at the bottom by the pin D, Attached to this 0 3 very nearly to the outside of the still, and provided on their lower edgewith a steel brush or comb; These arms are adjusted to revolve near the bottom of the still, so that the steel brush is constantly scraping the bottom, Whatever may be the inequalities.

F Fis an air-pipe coiled inside the fire-box B, and conducted so that the discharge is inside and near the bottom of the still. G is the shaft are the arms or paddles E E, reachingfeed-pipe; 11H, vapor-pipes; I andK, dissame time a current of air is forced through the pipe F, and,becom.ing heated in its passage through the coil, is discharged .into the oil, thus assisting to agitate and heat it, improve the color, and at the same time facilitate the passage of the vapor through the pipes H H. As the quantityof oil is reduced by vaporization fresh oil is introduced through the pipe G. 5 5

As the residuum (either tar or lubricating-oil, as may be desired) collects in the still, it may be drawn off through the pipe I \vithoutstoppin gthe operation of the still; or the machinery may be'stopped, fires drawn, and the still entirely emptied through the pipe K.

I disclaim the invention of revolving arms or paddles used for thepurpose of agitating the oil, only to use it as a part of the combination herein-described.

: The process of continuous distillation is not new; neither is the introduction of hot air into the still for the purpose of lugging over V the vapor; but my combination of mechanical forces with hot air discharged into the body of the fluid and furnace-heat, increases the agitation ofthe oil, prevents burning, and produces certain effects upon it, making boththe distillate and residuum more valuable, as hereinbefore described. I 7

I claim as my invention- A A stillfor refining petroleum or hydrocarbon oils, consisting of the vessel A, central revolving shaft, 0, with arms E E, thearms be- .ing provided with a steel brush or comb on 8 their lower edge, and so adjusted that the brush shall be constantly in contact with and scraping the bottom of the still, hot-air pipe F F,

feed-pipe G, vapor-pipes H H, discharge-pipes I and K, and furnace B for continuous-distil- 85,

lation, substantially as described, and for the purposes herein set forth.
